1/7 Did you ever need to run a piece of C# code on Windows 3.11? Me neither, but I did it anyway. A thread. 
2/7 The key ingredient it setting your expectations low. This is the program I got running:
3/7 I started where my "8 kB selfcontained game in C#" exercise finished: with a way to build fully native C# executable with no dependencies:
4/7 Once you get a piece of C# compiled to native code with so few dependencies, it becomes easy to do weird stuff with it.
5/7 Okay, so we can compile C# to small 32-bit or 64-bit native binaries. How does that help on 16-bit Windows?
6/7 Glad you asked. In 1992 Microsoft shipped an addition to Windows 3.11 called Win32s. This let people run *some* 32-bit apps on the otherwise 16-bit system. Not all Win32 APIs were available, but surprisingly many apps still worked with it. Like Office 95.
7/7 Turns out the object files produced by the CoreRT ahead of time compiler from 2020 can still be linked with the linker that shipped with Visual C++ 2.0 in 1994. So it's C# compiler -> CoreRT Compiler -> Linker -> Success.
